Connecticut Natural Gas (CNG) is a natural gas distribution company that delivers natural gas and energy services to residential, commercial, and industrial customers in the Greater Hartford area and Greenwich, Connecticut areas. CNG is a subsidiary of UIL Holdings Corporation, headquartered in New Haven, Connecticut.[1]
CNG's service territory in Connecticut includes the cities of Hartford and New Britain, Connecticut, as well as the communities of Avon, Berlin, Bloomfield, Canton, East Hartford, Farmington, Glastonbury, Manchester, Newington, Rocky Hill, Simsbury, Unionville, West Hartford, Wethersfield and Windsor in Hartford County; Hebron and Mansfield in Tolland County; Portland in Middlesex County and Greenwich in lower Fairfield County.
The relocation of CNG's headquarters from Adrien's Landing to East Hartford cost $37 million which was paid for by the state.[2] The move was controversial because the contractor chosen to do the job (Tomasso Group) had a corrupt relationship with then Governor John G. Rowland, who was overseeing the development of Adrien's Landing, that eventually cost him his job.[3] Tomasso Group principal Angelo Tomasso Jr. also served on the CNG board at the time.[4]
Employees at CNG are represented by Connecticut Independent Utility Workers.
